折弯方向　
Bend direction

铜合金的折弯加工性取决于材料的压延方向。折弯直线与压延方向正交时为Good Way，平行时为Bad Way。

Bend formability of copper alloys depends on rolling direction. Bends with the axis transverse to the rolling direction are defined as good way bend; bends with the axis parallel to the rolling direction are termed bad way bend.
